This atlas provides an accurate and detailed depiction of all brain structures at fetal stage E17.5, Day of birth, and Day 6 postnatal. In addition to brain structures, the atlas delineates peripheral nerves, ganglia, arteries, veins, muscles bones and other organs. It is an indispensable guide for the interpretation of nervous system changes in gene knockout and transgenic mice. The authors are recognized leaders in brain cartography, and the delineations and graphics link the atlas with other highly successful Paxinos atlases, complementing the catalog of brain atlases of highest quality available from Elsevier. There is currently no alternative of similar quality and extent on the market.
